Django vs. Flask

Django vs. Flask

There’s never a rule of thumb in opting for either technology and if you ask a software engineer you’re likely going to hear that it’s more the matter of a tech religion than of weighing pros and cons. Though there’s a way to outline some use cases.

** Django is for bigger projects, which is not always true **

Django is aimed at larger and scalable projects, which can be launched right away. You don’t have to configure an entire product infrastructure as most of the needed tools go out-of-the-box:

  • forms
  • database administration
  • authentication
  • templating
  • routing, etc.

The “batteries included” approach lays grounds for fast development though doesn’t provide enough flexibility. Once there’s a need for exact systems and workflows you may spend more time configuring them for which Flask is a much better tool.

** Flask is not only for small apps either **

Flask is a microframework and initially aims at smaller products as well providing more flexibility. Now, Flask can be used for extensive platforms and functionalities as well. According to our experience, applying Flask is reasonable for systems with intricate — and more importantly — highly custom functions supported. Django is very solid and any step outside of its competencies will be a challenge.
In order to successfully operate Flask in complex systems, you’ll need a highly skilled expert to plan an infrastructure and understand how all processes work (which is essential for any big project, anyway).

** Community matters **

Django has reached its maturity and grown with various extensions and bundles that cover a large variety of features. Moreover, its community is quite active, which allows developers to resolve most of the occurring issues. Flask is 6 years old and has 15 times smaller community at StackOverflow only than Django.
